PURPOSE:  For diagnosis of pulmonary tuberculosis world over in patients having cough of more than 3 weeks, 3 smear examination preferably within two days are recommended. Beside the cost of sputum smear examination : an indirect cost of travel/cost of staying overnight, loss of wages of patient & sometimes of attendant is involved. Moreover, many patients fail to turn up for sputum examination next day or fail to come altogether on programme basis. A new method to avoid above disadvantages is need of day. Sputum induction as a method to avoid above disadvantages was studied.

METHODS:  Sputum smear examination of 130 patients having cough of more than 3 week was undertaken by standard protocol or by sputum induction using Jet Nebullizer and Salbutamol Solution was undertaken. Results of two methods were compared.

RESULTS:  Sputum smear was positive in 22 cases using sputum induction and 15 cases by standard method out of 130 cases. In only 9 cases, sputum was positive on day one by conventional method. In 15 cases out of 22 sputum positive cases gradation of sputum improved after sputum induction when compared with spot specimen. No complications using sputum induction were encountered. 20 (15.4%) cases out of 130 patients failed to turn up next day.CONCLUSIONS: Using sputum induction the results and gradation of sputum smear examination can be improved and results can be made available on same day. Disadvantage of cost of travel, cost of stay, loss of wages of patient and of attendant for giving 2nd early morning and 3rd spot specimen on second day can be eliminated. Sputum induction is cheap, easy to perform and is devoid of complications.

CLINICAL IMPLICATIONS:  Sputum induction can be employed instead of conventional method for diagnosis of pulmonary tuberculosis by smear examination as a cost effective method in field setting.
